IMPROVED APPARATUS FOR CARBURETING AIR.

Specification forming part of Letters Patent No'. 57,164, dated August14, 1866.

drawings, which are made part of this specification, and in which-Figure 1 is a transverse vertical section through the center of themachine. Fig. 2 is a vertical transverse sect-ion of the regulator atits full height. Fig. 3 is a front elevation.

Fig. 4 is a perspective view of a portion of the air-forcing wheel,showing the open end. Fig. 5 is a longitudinal vertical section of themachine. Fig. 6 is a side elevation.

The invention consists of a machine through i which a body1 of air isforced by a motor,

(weight, for instance,) and is caused to circulate against surfacescharged with hydrocarbon liquid for the purpose of carbureting it.

`The peculiar features of the machine consist- First, of an air-forcin gcylinder or chamber revolving in a tank within a revolving carbureting-cylinder which revolves Within the hydrocarbon reservoir and carriesup a portion of hydrocarbon for exposure to the air which circulatesthrough the machine.

Second, it also consists of a regulatingchamber so placed above themachine and op erated by the iniiux of gas thereinto as to close thepassage of gas from the machine and stop its operation till the pressureis relieved by removal of gas from the regulatingchamber.

Third, it also consist-s of a central displac ing-chamber placed withinthe air forcing cham ber and provided with radial arms which connect itwith the exterior case.

Fourth, the carbureting-cylinder provided with a reticulated orpermeable surface, and with lifting cups or receptacles on its insidefor dripping upon the air-forcing wheel.

Fifth, the semi-cylinder or chamber placed within thecarbnretingcylinder occupied by the air-forcing wheel, separating theiluid in which the latter revolves from the lrydrocarbon iuid in whichthe carbureting-cylinder revolves.

Sixth, the provision of hanging lamp-wick or analogous material withinthe air-forcing vheel when the latter revolves in hydrocarbon uid.

In the drawings, A, Fig. 1, represents acyl inder or other shaped vesselof metal, closed at each end, and made perfectly air-tight bystuffing-boxes where the spindles pass through the ends, and supportedupon aframe, a c a a. One of these spindles, b', is shown having apinion and train, c c, of wheels working in connection therewith torevolve the air-forcing wheel C, which is affixed to the spindle andrevolves with it.

The air-forcing wheel C is provided with Wings radiating from a centralcylinder, c, which divide the space in the air-forcing wheel intosections of the required number.

Atthe upper edge, where joined to the periphery of the wheel, the radialarms are so arranged by bending as to make one side edge in advance ofits opposite. To the outer edge of the radial arms there are solderedwings, extending from the center to periphery and equal in surface tothe spaces between each pair of arms, one edge only being soldered toeach arm, and its opposite being an inch or more at the periphery of thewheel from the arm to which it extends, as shown at Z, Fig. 5, and inthe perspective view, Fig. 4. The end of the wheel nearest the gearingis closed by a metal disk or cover from center to periphery, solderedthereto and made-air-tight.

The air-pipe d, Fig. 5, is a metal tube bent in the form therein seen,one end being soldered to the cover of the cylinder, andthe otherpassing through the end of the cover of the wheel C up to neantheperiphery of the wheel. In the center of the air-pipe there is .athimble soldered for the spindle to pass through, as shown, and thecover of the wheel has an opening in the center large enough to revolve.

with duid gasoline or a heavier hydrocarbon,

or with water.

The carbureting-drum D revolvesupolfa spindle, d', which enters at oneend the spin' dle revolving the air-forcing wheel, andat other passingthrough a stuffing-box on the outside case. The two spindles, arrangedas seen in Fig. 5, passing through the stuffingboxes, render them rigidand capable'of supporting the wheel and carbureter.

The carbureting-drum D is made of perforated metal or any frame-Work,and may be covered with felt or other porous substance, or may have areticulated or perforated surface, for the purpose of exposing a largersurface to the action of the vapor. This drum is provided witli caps orreceptacles on theinner surface to raise np and drip the hydrocarbonliquid upon the wheel G, and revolves in hydrocarbon fluid, While theair-forcin g wheel revolves in separate fluid, and the two are arrangedto revolve in the same or in opposite directions, and the drum, byseparate gearing K Z and link-band fm, in connection with the spool Iand cord and Weight which give itl motion, may have a faster or slowermotionv than the air-forcin g wheel, or may be attached to the spindleb.

The regulator F is a vessel of any shape, closed at each end, havingaslot or opening, as seen in Figs. 1, 2, and 5, sufficiently wide toadmit of the pipes G and H and the requisite play of the regulator fromside to side,

l l when supported upon a shaft connected with one edge of said slot,the shaft passing through a stuffing-box on one end of the close vesselE, Which contains the regulator, and at the other Vresting in a box orjournal within said vessel E. y

The shaft, which supports the regulator F and is the fnlcrum upon whichit turns, has a small pulley-wheel, 0, 0r lever on its outer end, which,by a band, operates upon a still smaller pulley, p, attached to aspindle, to which is connected the regulator-valve R within the pipe G.

, The regulator-chamber E is lled with tluid,` l

as shown, to any height which may be found most desirable, and has anoutlet-opening on thetop for the admission or escape of air.

There are suitable openings in the machine for filling or emptying eachof the several parts with the iiuid required, which will be easilyunderstood.

The operation of the apparatus may be understood by supposing theair-forcing Wheelchamber B lled with fluid .to just cover the air-tightor solid vessel o, the outer chamber, A, with hydrocarbon iluid to anyheight above lor below the spindle which may be desired.

The regulating-chamber is also supplied with iinid, as before explained.Weight being applied to the cord, the spool I, revolving, gives motionto the train of Wheel-work connected with the air-forcing wheel (l,which, drawing air from the action of its radial Wings and propellersthrough the pipe d, forces it into the chamber A, when, by passing overand through the perforations in the drum I), it is thoroughly carbnretedbefore passing through the pipe G into the regula-tor F, from whence itpasses through the pipe H, to be used for the purposes of illuminationor otherwise. The action of the regulator may be understood by supposingit illed'. By pressure of the air-forcing wheel it would be raised byturning on the fulcrum described, operating at the sameAtime on theregulator-valve R to partially or wholly close the pipe G, through whichthe vapor passes into the chamber F. Upon the removal of the pressurewithin through escape of or consumption of the gas in the pipe H, theunequal balance of the regulator would cause it to fall to the positionshown in Fig.1, and the valve R would be again open fully for theadmission of a further supply of vapor.

It willY be also seen that when there is no escape going von through thepipe H there can be no motion of the air-forcing wheel, it being heldstationary by the pressure within the chamber A and regulator F.

The spindles b and d', Fig. 5, may be connected or revolvedindependently. In the former case the three stufling-boxes describedwill be necessary, and the train of wheels c" and c from the spool Iwill be sufoient; but when disconnected the spindle d will be rotated bythe band m on the drums 7a l, and the middle stufiing-box may bedispensed with.

rlhe drip from the cylinder keeps the chamber B sufficiently full tooperate well when once started right. The chamberB may overiow into AWithout injury.

This apparatus may be used by the pressure of gas from the gas-main,instead of being revolved by mechanical appliances attached to theair-forcing Wheel; or the two may work in unison.

1 What I claim as new, and -desire to secure by Letters Patent, is-

1. The air-forcing chamber C, revolving in the tank B, which issurrounded by the reservoir A, in which the carbureting-cylinder or itsequivalent revolves.

2. The inverted chamber F, vibrating upon the axis and actuated by thevarying pressure of the gas contained therein, to operate as ,aregulator, substantially as described.

X 3. rllhe displacing-chamber c in the chamber G, operating asdescribed.

4. The carbureting-cylinderD, provided with cups or receptacles on itsinner side, and with HUGH L. MGAVOY.
